Breathe through your nose at night—> tape your mouth

Of all the things I’ve tried, taping my mouth at night has had the greatest positive impact on my health. I would argue that this entire website and all of my research is the result of the energy I gained from taping at night. Of course, not everyone will respond in the same way I did. But, taping requires very little effort for the health benefits it provides. Therefore, I believe Principle 2 is not only the easiest, but the most important of them all.

“Therefore, the diabetic subjects examined have a loss of the parasympathetic tone during nighttime and hence a marked prevalence in sympathetic tone both during day and night without day-night changes in sympathovagal balance.” - Bernardi et al. (1992)

“While asleep, shut your mouth and save your brain.” - Sleep (1983)

Practice Principle 2

I started using generic paper tape I purchased from the local pharmacy, then moved to 3M micropore tape that I bought on Amazon. Now, I use Lipsealtape because it does not dry out my lips and is easy to remove in the morning. If you are nervous about taping, try it out during the day so you can see how it feels.

WARNING: Don’t tape your mouth shut if you’re sick, after drinking alcohol, if you are taking sedative medications, if you have difficulty using the tape during the day, or if you have difficulty with breathing through your nose in general (consult your physician in that case).

Finally, in the beginning you’ll probably notice that the tape does not stay on the entire night. This is normal. As you get used to nasal breathing at night, the tape will gradually stay on longer and longer, until you eventually keep it on all night.
